Visibility tool not working with dynamic landscape material

Hello,

I’m trying to use the visibility tool to make a whole for a cave system. My project uses a dynamic instanced landscape material I created using a tutorial by ratspawz UE4 Landscape Material Summary - YouTube

I have followed the tutorials on using the visibility tool including the one by Epic Unreal. When I click on the area I want the hole, no hole appears and the entire quadrant changes to the grass layer.

Is it possible to use the visibility tools when you have used and instanced material (three rock, dirt, grass)?

Any help would be appreciated. I’ve searched the web and haven’t found an answer yet.
